Digital Link

This is the only way to use a chronograph. Great design. Easy to use and take notes with. Great calculations. Between this and the Hornady 4DOF app you’ve got all you need.

I had it on dark mode and aftet update it reverted to white and I can't find any setting to change it back.

This app was very useful until I upgraded my iPhone to iOS 17.3. It no longer works. When trying to connect a message on the phone says, “Digital Link not supported“. Hey developer, how about fixing this?

Works great on both my iPhone and iPad! So far, after about 150 shots, it has called every one of them!

I do a lot of load development and a good chronograph needs good software, this app is excellent. It allows not only Bluetooth recording of chronograph results, but logging of load data for future analysis. User interface is friendly and functional. I would pay for this app.

This app worked great and i could import files to Gordons Reloading Tool for load development. Not now. Only can export PDF which is useless because it isnt data. Look and feel changed too so i suspect someone dropped a line of code…..please fix!

With the latest update, I can’t view images any longer. I’ve saved a ton of group images and now the only option is to “Remove” or “Choose” a new image. The thumbnail is too small to be of value.

One it the worst updates ever - would not purchase again - must be someone out there who listens to their customers and wants to make a product that is improved- not headed backwards

App worked great to start, now my iPhone says that it is not compatible and only works some of the time.

Not sure why this app has not received better ratings. I just got my ProChrono DLX bluetooth version (obviously) and put 8 .25 caliber pellets through it without a glitch. Great readout with large numbers on both my phone and my Macbook Pro. The app is easy to navigate and gives you all the info any serious shooter needs regarding projectile velocities (fps) and foot pounds of energy (fpe). Lots of good stuff to know when modifiying any firearm or air rifle.
